3-2 Troubleshooting
3.2 Improper Network Cabling and Topology
Improper network cabling or topology setup is a common cause of poor network performance and
network failure.
Table 3-4 Troubleshooting Improper Network Cabling and Topology
DESCRIPTION PROBLEMS AND CORRECTIVE ACTION
Faulty cables Using faulty network cables may affect data rates and have an impact on your network
performance. Replace with new standard network cables.
Non-standard network
cables Non-standard cables may increase the number of packet collisions and cause other
network problems that affect your network performance. Refer to Table
2-2 for more
information on network cable types.
Cabling Length If you use longer cables than are needed, transmission quality may be affected.
The network cables should not be longer than the limit of 100 meters.
Too many hubs
between the computers
in the network Too many hubs (or repeaters) between the connected computers in the network may
increase the number of packet collisions or other network problems. Remove
unnecessary hubs from the network.
A loop in the data path A data path loop forms when there is more than one path or route between two
networked computers. This results in broadcast storms that will severely affect your
network performance. Make sure there are no loops in your network topology.
